Simplify : (1)sqrt((256)^((1)/(4)))(2)(1)/(4)(128)^((1)/(3))

If (1+a)(1+a^(2))(1+a^(4)) . . . . (1+a^(128))=underset(r=0)overset(n)suma^(r ) , then n is equal to

If (1+a)(1+a^(2))(1+a^(4)) . . . . (1+a^(128))=sum_(r=0)^(n) a^(r ) , then n is equal to

Find the values of the following correct to five decimals. (1)/(root(3)(128))

Statement-1: The remainder when (128)^((128)^(128)) is divided by 7 is 3. because Statement-2: (128)^(128) when divided by 3 leaves the remainder 1 .

If1+r+r^(2)++r^(n)=(1+r)(1+r)r^(2))(1+r^(4))......(1+r^(128)) then
